Title: Danger preventing device for vehicle
Inventor: HACHIMAN YASUHIRO
IPC: B60R21/34
Filed: 1989-07-28
Abstract: PURPOSE:To prevent a door from collision with a moving object due to allowing the door to unintentionally remain opened when a passenger gets out of a vehicle by restricting the action of opening the door when the presence of the moving object is detected in the rear of the vehicle according as the door is opened. CONSTITUTION:When a door is opened at the time that a passenger gets out of a vehicle, a door switch 14 operates to detect the partly opened state of the door, and a control circuit unit 10 starts to hold the door in the standby condition. When the door is further opened under this condition, a sensing sensor 7 detects the range of visual field in the rear of the vehicle. When the sensing sensor 7 detects, for example, a moving object such as a car, etc., within the sensing distance, the control circuit unit 10 drives and controls a solenoid 8 to restrict the action of opening the door. At the same time, the control circuit unit 10 drive-controls a buzzer 13 to inform the passenger the presence of the moving object in the rear of the vehicle. Thus, accidents such as collision of the door with the moving object, etc., due to allowing the door to unintentionally remain opened at the time that the passenger gets out of the vehicle, can be prevented.

Abstract: PROBLEM TO BE SOLVED: To prevent or remove the drying of the ink residual matter in the image recessed parts of a plate cylinder in a post-rotary sector by forming a peripheral direction gap filled with ink by a flexible ink guide apron in cooperation with the peripheral surface of the plate cylinder. SOLUTION: When the image recessed parts of the peripheral surface 11 of a plate cylinder 4 in a post-rotary sector pass through a nip 8, the ink residual matter in the image recessed parts is removed and the image recessed parts become empty. An auxiliary device 15 is provided in order to prevent the drying of the ink residual matter caused by the evaporation of the solvent of the plate cylinder in the post-rotary sector before the image recessed parts are again immersed in printing ink. The auxiliary device 15 supplies printing ink of the same kind as the printing ink 2 to the peripheral surface 11 of the plate cylinder 4 in the post-rotary sector. Therefore, the auxiliary device 15 is equipped with a flexible ink guide apron 16 and this ink guide apron 16 forms a peripheral direction gap filled with ink in cooperation with the peripheral surface 11 of the plate cylinder 4.

Title: Thermal head
Inventor: AOKI ATSUSHI
IPC: B41J2/36
Filed: 1986-08-26
Abstract: PURPOSE:To facilitate control of a heat generating area through varying applied energy and facilitate representing multiple gradations through multiple-valued recording, by setting the width of an electrode at the point of connection with a heat generating element to be not more than the effective recording width of the element, in a thermal head comprising a heat generating element array. CONSTITUTION:An electrode 2 is split into parts 2a and 2b in the vicinity of the point of connection with a heat generating element 1, with an intermediate part 2c between the parts 2a and 2b cut out. As a result, the width of the electrode 2 at the connection points 2a, 2b for the heat generating element 1 is smaller than the width of the element 1. Since the electrodes 2 are connected to both ends of the heat generating element 1, paths of electric currents in the element 1 are as indicated by arrows 3. Thus, some currents flow in diagonal directions in the element 1. Accordingly, the area 81 over which an ink is melted is varied as the duration of a pulse voltage impressed is gradually increased, whereby intermediate gradations can be represented.

Title: Method of cooling water-cooled engine
Inventor: HIRATA MAKIZOU
IPC: F01P5/06
Filed: 1983-10-24
Abstract: PURPOSE:To remove dust contained in cooling air efficiently, by constructing an engine chamber in a double-shell structure, and forming a cooling-air inlet opening having a large opening area and provided with a screen in the outer shell while forming a section for turning the flow of cooling air in the inner shell. CONSTITUTION:When an engine 5 is started, cooling air is drawn into the space formed between an outer shell 1 and an inner shell 2 of an engine room 4 through a screen formed in the outer shell 1. Large particles of dust contained in the cooling air are captured by the screen. Since the cooling-air inlet opening having the screen is formed to have a large opening area and the speed of cooling air passed through the screen is low, the amount of dust particles of small masses passed through the screen is reduced. Further, while the cooling air is passed to a flow reversing section 3, dust particles having large masses are dropped into a dust collecting pocket 9 but dust particles that are not reversed completely at the reversing section and brought into collision against a side wall 8a are dropped into a dust collecting pocket 8. Further, since the speed of cooling-air flow in the engine chamber 4 is low, dust contained in the cooling air is dropped to the bottom 4a of the engine room 4 while passing through the engine room 4. Thus, dust contained in the cooling air is removed completely.

Abstract: PURPOSE:To prevent generation of lead powder without breaking a lead by forming the end of a lead holder in a spherical shape except the peripheral edge of a lead feeding hole, and forming the inner edge of the lead feeding hole in a sharp edge. CONSTITUTION:A pen carriage has a relation to a feed actuator of a pencil lead. A predetermined writing pressure is applied to a pencil lead 20 at the time of plotting. When the end of the lead 20 is plotted in contact with a sheet surface A, the end 11 of a lead holder 10 is brought at the extremely small part of a lead feeding hole peripheral edge 12' into contact with the sheet surface, and the holder 10 is retracted at a distance corresponding to the wear of the lead 20 due to plotting. Accordingly, the end of the lead 20 is always plotted in a state contained in the lead feeding hole 12 of the holder 10 to prevent the lead 20 from breaking, and the inner edge of the hole 12 is formed in a sharp edge to substantially have no air gap, and hence lead powder is not stored. Of course, the end of the holder 10 neither rubs with a plotted line nor causes contamination of the sheet surface.
